Summary
Food-specific inhibition training effectively reduces explicit food evaluation, potentially aiding eating behavior regulation. However, effects on implicit evaluation and long-term outcomes require further investigation.
Area of Science:
- Behavioral Psychology
- Cognitive Science
- Nutrition Science
Background:
- Food-specific inhibition training is theorized to reduce food evaluation, potentially aiding eating behavior regulation.
- Understanding the impact of this training on food devaluation is crucial for developing effective dietary interventions.
Purpose of the Study:
- To synthesize current literature on the effects of food-specific inhibition training on food evaluation.
- To conduct a meta-analysis of relevant studies to determine the efficacy of this training method.
Main Methods:
- A meta-analysis was performed on 24 studies, encompassing 36 independent samples, 77 effect sizes, and 3032 participants.
- Robust variance estimation in random effects meta-regression was used to analyze the effect sizes.
Main Results:
- Food-specific inhibition training significantly reduced explicit food evaluation.
- The training did not significantly affect implicit food evaluation.
- The meta-analysis included 3032 participants across 24 studies.
Conclusions:
- Food-specific inhibition training can effectively decrease explicit food evaluation.
- Further research is needed to explore long-term effects, generalizability to untrained foods, and applicability to different populations, such as overweight or obese individuals.
